Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 4,908,665, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 4,908,665 | |
| -1 | -4,908,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,908,665.
Example:
1 x 4,908,665 = 4,908,665
and
-1 x -4,908,665 = 4,908,665
Notice both answers equal 4,908,665
With that explanation out of the way, let's continue. Next, we take the number 4,908,665 and divide it by 2:
4,908,665 ÷ 2 = 2,454,332.5
If the quotient is a whole number, then 2 and 2,454,332.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 4,908,665 | |
| -1 | -4,908,665 |
Now, we try dividing 4,908,665 by 3:
4,908,665 ÷ 3 = 1,636,221.6667
If the quotient is a whole number, then 3 and 1,636,221.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 4,908,665 | |
| -1 | -4,908,665 |
Let's try dividing by 4:
4,908,665 ÷ 4 = 1,227,166.25
If the quotient is a whole number, then 4 and 1,227,166.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 4,908,665 | |
| -1 | 4,908,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 43 | 79 | 85 | 215 | 289 | 395 | 731 | 1,343 | 1,445 | 3,397 | 3,655 | 6,715 | 12,427 | 16,985 | 22,831 | 57,749 | 62,135 | 114,155 | 288,745 | 981,733 | 4,908,665 |
| -1 | -5 | -17 | -43 | -79 | -85 | -215 | -289 | -395 | -731 | -1,343 | -1,445 | -3,397 | -3,655 | -6,715 | -12,427 | -16,985 | -22,831 | -57,749 | -62,135 | -114,155 | -288,745 | -981,733 | -4,908,665 |
